The diminutive Western Screech-Owl is a predator to be reckoned with: it occasionally takes prey bigger than its own body, including cottontail rabbits. At other times they’ve been seen eating bats, insects and earthworms, which they collect from rainy roads and even compost piles.
Western Screech-Owls sometimes perch at the entrance of their roost holes during the day, but they remain nearly invisible by pressing their head and body feathers against the tree to blend in.
Forages at dusk and at night. Hunts mostly by watching from a perch and then swooping down to take prey from the ground or from foliage. Also catches flying insects in the air. Can locate prey by sound as well as by sight.
